We provide the results of studying internal structure and composition rocks Semeitau Delbegetei massifs located in Eastern Kazakhstan. It was previously believed that these have different ages were formed geodynamic settings. The U-Pb zircon age from monzonites quartz determined to be 249 ± 2 Ma, which showed same Early Triassic massifs. Both are composed monzonite–granite series with a signifi...

the halak abad prospect occurs in the northeastern part of central iran zone (sabzevar structural zone). in this investigation, geochemical evolution, age and source of part of northeastern iran magmatic arc (intrusive bodies) in halak abad area in the khorasan razavi province has been studied. the exposed rocks consist of volcanic rocks with andesite and dacite nature, limestone, plutonic rock...

iron mineralization of kalate shahin is located 107 km on the ghoochan-neyshaboor road (in khorasan razavi province). subvolcanic intrusive bodies of quartz monzonite to monzonite porphyry intruded the cretacous limestone. sedimentary units of the area in decreasing age include cretaceous limestone and eocene and paleocene-quaternary microconglomerate to sandstone. mineralization in the region ...

The trace element composition of detrital magnetite grains recovered from six local streams around the Casino high-grade porphyry Cu-Au-Mo deposit, west-central Yukon, is compared with igneous and magmatic-hydrothermal mineralized unmineralized host rocks at deposit. Linear discriminant analysis 12 elements (Mg, Al, Ti, V, Mn, Co, Cr, Ni, Cu, Zn, Ga Ge) plots Ti versus Ni/Cr are used to discrim...

The area of study is located 120 Km north-east of Shahrood city. In terms of structure and geological classification, this area is located in the northern part of central Iran zone. Granitoids of Troud ranging from monzonite to granite. The main minerals of granitoids are quartz, plagioclase, and orthose. The accessory minerals are biotite, hornblende, sphene, and opaque minerals. Various textu...

The stability of tunnel site depends upon the deformation behaviors surrounding rocks, including joint density, mineral composition, micro cracks, and grain boundaries. aim this study was to analyze mechanical properties Besham Complex in Northern Pakistan terms petrography analysis. complex is prone as it bounded by Main Mantle Thrust (MMT) north, Thakot fault (Tf) east, Swat block west. In ar...

The Kalmakyr deposit in Uzbekistan is one of the world’s largest gold-rich porphyry Cu deposits, and mineralization was proposed to be closely associated with emplacement latest intrusive phases, that is, granodiorite porphyry. However, it still unclear which features these ore-bearing intrusions are crucial for enormous metal enrichment how they correlate magmatic fertility. In this study, we ...

The petrogenesis of aluminous A-type granites is a contentious subject. Here, we focused on the North Kudi pluton in Western Kunlun orogen to investigate origin and magmatic processes responsible for generating granites. Samples from are metaluminous weakly peraluminous. K-feldspar granite samples characterized by high alkali Cl contents, HFSE concentrations FeO/MgO, low F content, negative Ba,...
